Lawnmowerman Posted July 11, 2006 Report Share Posted July 11, 2006 Drill the head off the bolt with a 10mm bit then simply undo the threaded part with some grips. Quote Link to comment Share on other sites More sharing options...

Rebelistic Posted July 12, 2006 Report Share Posted July 12, 2006 Cut a line into the bolt and then try and unscrew it with a screwdriver I've done that before. I had to hit the screwdriver with a hammer though Might wreck the bearings but cheaper than wrecking the crank. Quote Link to comment Share on other sites More sharing options...
wayn3 Posted July 12, 2006 Report Share Posted July 12, 2006 Try a star tap,(for people who don't know what it is, its a stay shaped bit which u tap into the bolt, then you put like a handel onto the bit and unscrew it) i did on my crank bolts not that long ago.
